When someone in a relationship, continually talks to, or hangs out with someone to get all of the things they are missing in their unfullfilling relationship. This may sometimes lead to sex but instead of adultery, should be considered bestiality.
After a weekend with her bf, she spends the next 5 days with her emotional support animal, to get her self-esteem built back up.
1. A person that is having an emotional affair with someone, who is in a relationship with someone else.
That guy is her Emotional Support Animal. He listens to her, takes her out, is romantic, all of the things she doesn't get in her own relationship.
